产业投资变动与边际碳生产力的作用关系及实证研究

Mechanisms and Emprical Amalysis of Industrial Investment and Marginal Productivity Carbon

首先界定了边际碳生产力内涵,以该指标表示经济增长与CO2排放协调发展状况;然后利用投资消耗系数矩阵实现各产业部门固定资产投资与固定资本形成额的相互转化,并将转化关系与里昂惕夫静态投入产出模型相结合,从而确定产业投资变动与边际碳生产力的作用关系与机理;最后利用2007年中国投入产出数据,实证研究了各产业部门投资增加1亿元所产生的边际碳生产力。研究发现:不考虑能源消费结构变动时,其他制造业投资所产生的边际碳生产力最大,批发零售贸易和住宿餐饮业投资所产生的边际碳生产力最小;能源消费结构变动后,其他制造业投资产生的边际碳生产力最大,食品制造业投资产生的边际碳生产力最小;各能源得到充分利用和能够相互转化条件下,焦炭使用数量的增加更有助于提高碳生产力。

Firstly,marginal productivity of carbon is defined,and with this indicator to indicate coordinated development of economic growth and CO2emissions,and then use of investment consumption coefficient matrix to implements various sectors of fixed asset investment and the amount of fixed capital formation into each other,and combined this transformation relationship with Leontief static input-output model to determine effect relationships and mechanisms of industrial investment changes and marginal carbon productivity.Finally,using of the 2007input-output table to do some empirical study on marginal carbon productivity generated 100million yuan investment of each industrial sectors.It concludes that if do not consider the energy consumption structure changes,other manufacturing investment generated the largest marginal carbon productivity,and investment of wholesale and retail trade and accommodation and catering industry generated the smallest marginal carbon productivity;If energy consumption structure changes,other manufacturing investments generated maximum marginal carbon productivity,food manufacturing investments generated the smallest marginal carbon productivity;each energy to be fully utilized and can be transformed into each condition,the increase in the number of coke use more help to improve carbon productivity.If the energy is to be fully utilized and can be transformed into each other, increase in the number of coke use helps to improve carbon productivity.
